Which group comprises long flat neck muscles located lateral and anterior to the thyroid lobes?

• A. Strap muscles
• B. Scalene muscles
• C. Infrahyoid muscles
• D. Suprahyoid muscles

Answer: (A)

Strap muscles are the long, flat muscles that run along the front of the neck and lie superficial and lateral to the thyroid lobes. This group, also known as the infrahyoid muscles, includes the sternohyoid, sternothyroid, thyrohyoid, and omohyoid. Their slender, ribbon-like shape and position directly in front of the thyroid gland explain why they’re described as long, flat muscles located lateral and anterior to the thyroid lobes. The other options don’t fit this specific description: scalene muscles sit more laterally and deeper in the neck, away from the thyroid; suprahyoid muscles are located above the hyoid bone; and infrahyoid describes the broader group, but the characteristic long, flat, strap-like muscles in front of the thyroid point to strap muscles.
